Soon has mixed quite a few colors, and tired dyeing on the gauze and printing cotton material. And there are several findings we found out:

The left is the one he dyed on the gauze. It was mixed of the only the two thermochormic inks, actually the heat spread is quite fast for gauze as it is very thin. But from experiment, the part that is heated up turned white straight away without any intermediate color. I deduced the problem might be because the color he dyed is not strong enough; and also the blue which reacts at 31 degree is not strong enough so we cannot see the mixed color changing from magenta and then to white.

I went to power lab another time to test out the temperature sensor accuracy. And the graph is like this:
